BURNER.

SPECIFICATION forming part of Letters Patent No. 783,161, dated February21, 1905.

Application filed May 22, 1902. $erial No. 108,661.

To (bl/Z whom, it may concern.-

Be it known that we, LOUIS B. VVnBs'rsR and HARRY B. WEBSTER, citizensof the United States, residing at Los Angeles, in the county of LosAngeles and State of California, have invented a new and useful Burner,of which the following is a specification.

This invention relates to heating apparatus, and particularly to burnersconstructed to consume liquid fuel; and some of the objects of theinvention are to provide a burner of this character which will be simpleand cheap in construction and effective for the purpose designed.

Another object of the invention is to provide a burner constructed to beregulated by one valve, which controls the supply of fuel, and toprovide a burner so constructed that access may be gained to theinterior thereof by a partial rotation and subsequent removal of the topor dome of the burner.

Furthermore, an object of this invention is to provide a retort orvaporizer wherein no overflow of oil is required to ignite or start theburner, whereby the burner and adjacent parts are always clean.

With these and other objects in view the invention consists,essentially, in the construction, combination, and arrangement of parts,substantially as more fully described in the following specification andas illustrated in the accompanying drawings, forming part of thisapplication, in which Figure l is a central sectional view of a burnerembodying some of the improvements.

Fig. 2 is a top plan view of the same. Fig. 3 is a sectional view of aburner of slightly-different contour and constructed with an increasedheating-surface for the fuel employed. Fig. 4 is a top plan view of thesame with the cover or dome removed. Fig. 5 is a central sectional viewof still another form of burner wherein an air-inlet is employed; andFig. 6 is a side elevational view, partly broken away, illustrating thelocking means employed.

Similar characters of reference designate corresponding parts throughoutthe several views.

Referring to the drawings and particularly to Figs. 1 and 2 thereof, thereference character l designates a retort orvaporizer, preferablycircular in form and desirably embodying an upper portion or dome 2,which may be provided with an angular extension 3 to receive a wrench orother device for the purpose of turning or rotating the dome when it isdesired to disconnect the same from the lower portion 4 of the retortorvaporizer, as hereinafter more fully explained.

The lower or bottom portion of the retort or vaporizer is preferablyconstructed with an interior tubular extension 5, constructed to receivea fuel-pipe 6, having connection with the Source of fuel-supply, (notshown,) and the fuel-pipe 6 is preferably provided with a valve 7, ofany suitable formation, by means of which the supply of fuel can beregulated and the heat of the retort or vaporizer controlled.

Adjustabl y or otherwise secured in the bottom portion 4, preferablyaround the fuelpipe 6, Fig. 4 of the drawings, are burnertubes or outletdevices 8, desirably terminating in a plane above the orifice of thefuel-pipe 6 andconstructed with lateral ports or openings 9 tofacilitate the passage of the gas generated within the retort orvaporizer into, through, and out of said burner-tubes, substantially ashereinafter set forth.

The upper and lower portions of the retort or vaporizer are preferablyprovided, respectively, with an annular tongue or rib 10 and an annularrecess or groove 11, constructed to receive said tongue so as to form atight joint or connection between the parts of the retort or vaporizer,and, if desired, packing may be employed between the parts, and theupper portion 2 is preferably constructed with lateral projections orlugs 12, any number whereof may be employed to engage the inclined faceor edge of recessed lugs or sockets 13 upon the lower portion 4. (Seeparticularly Fig. 6 of the drawings.) By means of this construction theupper and lower portions of the burner are removably connected and maybe readily disconnected by a slight rotation of the upper portion 2 bymeans of a wrench or other tool engaging the angular extension3 upon theupper portion or demo 2 of the retort or vaporizer without the use ofbolts, screws, and similar devices, which are injured by the intenseheat to which the parts are subjected. v

Adverting to Figs. 3 and 41: of the drawings, there is illustrated aslightly-modified form of the construction hereinbefore described andshown, wherein the contour or exterior configuration of the retort orvaporizer is somewhat changed, as may be done in practice withoutdeparting from the invention.

In Figs. 3 and 4 the burner therein illustrated embodies a flat circulartop or cover 15, having an angular extension or turning portion 16, andthe annular depending rim 17 of the top portion is preferably providedwith an annular rib or tongue 18 to enter an annular recess or groove 19in the edge of the bottom portion 20, which is preferably constructedwith a receding central portion 21, wherein is mounted asuppl y or fuelpipe 22,and burnertubes or outlet-pipes 23 may be adjustably or rigidlymounted in the bottom portion 20, around the receding center thereof,substantially as shown in Fig. 4c of the drawings.

By constructing the bottom portion 20 with a receding center the heatingsurface or area thereof is increased and the greater amount of fuel issubjected to heatand is thereby more rapidly volatilized, as will bereadily understood.

The operation of the invention as far as the same has been describedwill be readily understood from the foregoing description, when taken inconnection with the accompanying drawings and the following explanationthereof:

The liquid fuel, preferably oil, is introduced through the valvedfuel-pipe into the retort or vaporizer until a sufficient amount of fuelshall have entered the retort or vaporizer, whereupon heat is applied tothe bottom portion of the retort or vaporizer around the fuelpipe, bymeans of a torch or otherwise, until the oil within the retort orvaporizer shall have become volatilized and the gas therefrom escapesthrough the outlet-pipe and ignites from the flame of the torch,whereupon the valve in the fuel-pipe isagain turned on and the fuel isallowed to flow into the retort or vaporizer, where it is converted intogas by the heat from the gasburning at the lower extremities of theburner-tubes or outlet-pipes, as before stated, and the accumulating gasin the upper portion of the retort or vaporizer is forced down throughthe outlet-pipes, thus creating a supply to maintain combustion at thelower extremity or orifice of the outletpipes, as will be readilyunderstood. By means of this construction the heat from the burning gasvolatilizes the fuel in the retort or vaporizer and produces more gaswithin the retort or vaporizer, which is forced outwardly to be burnedat the orifice of the burner-tubes.

In Fig. 5 of the drawings there is illustrated a modified form of theconstructions hereinbefore described and shown, wherein a retort orvaporizer substantially similar to that illustrated in Figs. 1 and 2 ofthe drawings is shown; but in this construction the retort or vaporizeris provided with an air-inlet or draft tube 25, located in the bottomportion of the retort or vaporizer, and it preferably extends below thefree end of the outlet-pipes upon the outside of the retort or vaporizerand above said pipes upon the inside of the retort or vaporizer in orderthat the air or draft may be taken into said pipe 25 below the flamefrom the orifice of the outlet-pipes and liberated within the retort orvaporizer above the gas therein, the air being drawn into the burner orretort by the action of the'gas escaping through the burner-tubes, aidedby the atmospheric pressure, so as to burn commingled gas and airinstead of gas alone.

It is not desired to confine this invention to the specificconstruction, combination, and arrangement of parts herein shown anddescribed, and the right is reserved to make all such changes in andmodifications of the same as come within the spirit and scope of theinvention.

We claim 1. A retort provided with an upper and lower portion havingengaging lugs, said lower portion having a central interior extension, afuel-pipe mounted in said extension so that the fuel will flow down thesides thereof, and burner-tubes surrounding said extension andfuel-pipe.

2. A retort having a bottom constructed with a central frusto-eonicaldepressed portion, whereby increased surface is provided for the actionof the heat, a fuel-pipe in said depressed portion and dependingburner-tubes mounted around said depressed portion.

In testimony whereof we have signed our two subscribing witnesses.
